SPECIFICATION forming part of Letters Patent N0. 397,798, dated February 12, 1889.

Serial No. 275,071. (No modeld To @ZZ whom it may concern.-

Be it known that I, ALONZO JOHNsOnL'a citizen of the United States, residing at Springtield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Gumming Devices for Envelope-Machines, of which the following is a specification.

The present improvenicnit in envelope-inachines relates to devices to be operated, in conjunction with the main gummer or picker, for the purpose of gunnnng a portion of one end of a fiap of a l1igl1-cut-envelope blank, whereby, when said one end flap is folded over to lie by its end over the end portion of the other end Iiap, it will be pasted thereto and at a portion thereof lying nearly upto the line of fold for the seal-flap, the back overlapping' iiap of the blank, as well known, usually overlapping and being secured to the eilges of the end flaps slightly; and the present invention consists in the combination and arrangement of the various parts, all substantially as will hereinafter more fully appear, and be pointed out in the claims.

On reference to the accompanying' sheets of drawings, in which the present invention is illustrated, and in which similar characters of reference indicate corresponding parts in all the views, Figure 1 is a side elevation of some f parts at the front and top portion of an envelope-machine in connection with which the j present independent gunnning device is applied, some of the parts in said view being shown as broken away and in vertical section for better illustration. Fig. 1 is a horizontal cross-section of the device on line a o, Fig. 1. Fig. 2 is a front view ot' the parts shown in Fig. l. Fig. 3 is an enlarged view of the improved gununing device by itself and as seen from the opposite side thereof to that seen in Fig. il. Eig. +L is an enlarged back view of same, or a View as seen. at the opposite side l,

thereof to that seen in Fig. Fig. 5 represents an envelope-blank for a high-cut envelope, the portion thereof gummed by the employment of the present invention being indicated; andFig. 6 is a rear view of an en velope, showing the end and back iaps folded in place and to be hereinafter referred to.

In the drawings, Figs. 1 and 2, A represents rthe front end of the usual table 0f the envelope-machine; B, the front arch, in which are the usual bearings for the plunger-shaft O, which carries the pickers or gummers D for gumming the seal and back flaps of the envelope-blanks E, a pile of which in said iig ures is shown supported, as usual, on the platen F. The picker-plunger is reciprocated through the engagement with an attached strap thereon of one end of a link, o, which by its other end is connected to a crank-arm, d, on a horizontal rocker-shaft, G, supported in the means of a crank-arm thereon and av connecting-rod actuated by a cam on the main shaft, (not shown,) all as usual, common, and well known in envelope-machines at present in extensive use, and the said parts are shown and herein mentioned as above that the relations therewith of the devices of the present invention may be more readily ascertained.

Resting' on a supplemental support or table, l0, above the table A is an upright, 11, sel cured thereto, for carrying and guiding the operative parts of the present device, and having right-angled lugs 17 thereon at each slides a vertical rod, 13,-011 the intermediate portion of which rod is a clasp or slide-block, 14, pivoted to which intermediately thereof, f as. at 9, is a bar, 15, normally standing vertical and parallel with said slide-rod 13, spiral springs 1G 16, secured to and reacting between the outer ends of said bar and lugs 12 on the ends of said slide-rod, serving to maintain said bar vertically and to maintain the said block 14 suspended midway between the ends t of the slide-rod, so that on the block being moved either up or down the said rod is coni strainedv to move therewith, and the said slot, 18, in said upright, with which extended portion thereof one endV of a link, 19, is pivend thereof, through verticalbearings of which block 14 is extended through a verticalguide-- suitable bearings, f, and oscillated throughl otally connected, its other end beingI pivoted to the outer end et' a crank-arm, 20, on said oscilla-ting shaft (i. 'llie said upright is prou vided with an extended vertical tlange, 2l, having therein a vertical slot, 22, et' suitable length, through which passes itforward the horizontal portion et' the independent gummer fr, eontinuetl in a downward extension, 24, formed at its outer end with a gummingiace, ot a conteur to cover the portion et' an envelope-blanlc end flap, (ini'licated at 2li, Figs. 5 and il.) The upper end ot" the slot serves as a n abutment-stop l'or the glimmer te limit and modify its movement, as will be explained in connection with the following' description of the operation of the machine, and it will be apparent that the said end of the slot must be carefully located with relation to the threw of the guminer. As shown in the drawings, the picker D is nearly at its uppermost position, and the bleek 1t is slid up nearly but not quite into its uppermost position, se that the end face of the independent guinnier av is trent ot" and about level with the top of a gum-box, j, properly adjusted in relation thereto. As the block 14; by the connection described with the oscillating shaft is moved slightly and still farther upwardly to its limit, the horizontal portion Q23 oi the guinmer-arni .frabuts against the upper end el the slot E22 in the flange 21, said arm tilting by its outer end downwardly, dipping into the gum-box te receive a quantity et gum on its tace, the guminer with its bar 15 swinging on the pivot 9 of the block 1.1L, and at such time causing a ded ection of the springs 1G, the action of which when the block is slid downwardly again will tend to carry the bar inte its upright position, and when upright will maintain the gummer in its proper position for its straight downward projection against the blank, as seen in Fig. 1 and in the full lilies, Fig. 3, the dotted lines in said latter figure illustrating the dipping movement of the gunnner when raised; and, as will be noted in reference to said Fig. 3, the upper end, 30, et' the said iange 21 is inwardly curved or projected toward the edge et' the bar 15, which is recessed, as at 31, the upper edge of thc recess being downwardly and inwardly inclined, as at 32, such formations securing on the downward throw of the slide-bleek a positive movement of the bar 15 inte its upright position irrespective ot the action el' the sustaining-springs.

(ln the portion ot' the oscillation ol' the rocker-shaft G to secure the descent ol the picker l) the bleek 1l and pivotally cenneeted and spring sustained gumiiier are also carried downwardly, se as to be by its iace. pressed upon the indicated portion oi. the one end Hap, securing a gumining thereof simultaneously with the gumming, as usual, by the picker of the back and seal .flaps ot the blank. As will also be noticed in Fig. 3, the bar 15 is provided with an extended edge or flange, Shwhieh, in the up-and-down travel et' the bleek 1l, bar l5, and glimmer, assists te steadily maintain said parts in their vertical relations, as described, and yet does not .interfere with the (flipping movements ol the guminer and conjunetive parts.

lVhile a particular arrangement ol' paris has been shown and described ter spring-snstaining the giiminer rr, pvotally attached lo the reciprocating slide, normally in line .l'or presentment against the proper portion olf the envelope-blank, and vet to permit oli' a tilt er dip et' the giiinmer on its contact. with an abutment suitably applied :for suoli ceiitact therewith toward its upward stroke, tlieinvention is not to be limited te such particular term oi spring-sustaining appliances, as other springacting devices maybe applied liietween the piveted gummer and its carrier for t-he similar effect.
